I figured out when changing a box from a single-core hardware platform with FBSD 8.1-STABLE/amd64 UP kernel to a SMP kernel with a dul core CPU that a former 'stble' arragemnet of a AMD HD4830 and radeon/radeonhd driver became instable. Whenever I leave an X11 session returning to xdm's login screen, the box freezes and only reset can bring it back to life. My lab's box is still as reported months ago of the same problemacy. The box runs also FreeBSD 8.1-STABLE/amd64 and has a SMP kernel running. The graphics adaptor was a HD4670, now a HD4770. Exiting a session and returning to the login screen is the same, the box freezes. Also very strange is the behaviour when trying to use HAL and DBUS as introduced with the newer X11 port revision. With both radeon and radeonhd the box starts well, presents the login screen and is network accessible. But whenever I activate HAL and DBUS (with a copy of X11/xorg.conf of my private box and configuration which works which the same OS revision) the box dies immediately and freezes with a black screen when X11 tries to come up (the xdm in this case). Even with identical configs and DRI/EXA turned off explicitely the box freezes if hal and dbus are enabled (config is, as I mentioned, adjusted to work with dbus and hal as it does on my private box).
